Transient Javaspace (Outrigger) Performance

Hi Everybody,

On a performance test I conducted I got rather surprising results.

It appears as if it takes quite a large time span between the time an entry
is actually written to the space and until a 'taker' gets the entry
instance.

In order to perform the required measurements, I setup both the writer and
the taker on the same machine but in separate JVMs.



The 'writer' application writes 3 types of entries and the 'taker'
application takes every entry which comes into the space.

The 'writer' application prints out "System.currentTimeMillis()" to the
console before and after writing the entry.

The 'taker' application prints out "System.currentTimeMillis()" to the
console after taking the entry.



*It is important to state that both the 'writer' JVM and the 'taker' JVM
both have the entries class definitions on their class path. So no class
downloading is done.

*It is also important to state that the measurements taken were not first
time invocations. a "warm up" process was conducted before measuring

Is that reasonable performance for the Outrigger java-spaces implementation?

Thanks in advance,

I am not sure I have ever measured the inter-write/take time before,
but these times strike me as a bit long for Transient Outrigger. The
write times look a bit slow too.<br>
How big are the entries? How many iterations did you let the space and
clients warm up for? I asume the space isn't doing anything else?<br>
